Circulating water purification device

The utility model discloses a circulating water purification device which comprises a first controlled electrode and a second controlled electrode which are respectively used for generating positive and negative ions, a main power output module which is connected with the first controlled electrode and the second controlled electrode and is used for driving the first controlled electrode and the second controlled electrode to generate the positive and negative ions, a high-frequency signal generation module which is connected with the main power output module and is used for generating a high-frequency signal to drive the main power output module to work, and a main power supply module which is connected with the high-frequency signal generation module and is used for supplying working power to the circulating water purification device. By the adoption of the positive and negative ions which attract with each other, the circulating water purification device removes water scales from a water body, and the seco
